JPS6015853Y2 - Roof structure of prefabricated buildings - Google Patents

Description

[Detailed explanation of the idea] This invention relates to the roof structure of prefabricated buildings.

In conventional prefabricated sheds with gable roofs, holes were made in the roof plates and panels and connected to the ridge beam using L-shaped or J-shaped hook bolts, resulting in the following drawbacks.

(1) Since holes were drilled in the roof panels and paneling, there was a risk of rain leaking from these locations.

(2) Bolt connection work had to be done on the roof, making construction difficult and dangerous.

(3) Many hook bolts had to be installed to prevent wind from blowing up, which required a lot of effort.

Therefore, the purpose of this invention is to provide a roof structure for a prefabricated building that has excellent rain protection performance and is safe and easy to construct.

An embodiment of this invention will be described with reference to the drawings.

That is, as shown in the drawing, the roof structure of this prefabricated building has a pair of roof plates 3. Place the upper end edge, weld the roughly knot-shaped connector 5 to the lower surface of the board 4, fit this connector 5 into the hat-shaped ridge 2, and connect the connector 5 and the ridge beam 2. are connected from the indoor side with bolts 6.

In this case, the eave girder 1 has a central upper part cut out to form a ridge beam fitting recess 1a, and a pair of vertical pieces for connecting the ridge beam (not shown) are formed facing each other on both sides of the fitting recess 1a, The ridge beam 2 is fitted between these vertical pieces and connected with bolts 7 and nuts (not shown), thereby fixing the ridge beam 2 to the eave girder 1.

Further, the ridge beam 2 has bolt insertion holes 2b formed in its web portion inside the eave girder 1.

Further, the roof plate 3 is made of a folded plate member, and its upper edge is placed on the outer flange 2a of the ridge beam 2, and the other end is tilted gently downward toward both sides of the ridge beam 2.

The connector 5 is formed by bending the tips of both outer flanges 5b of the hat-shaped main body 5a downward to form a side door piece 5C, and the lower part of this side door piece 5c corresponds to the bulge 3a of the roof board 3. A notched recess 5d is formed, and a screw hole 5e corresponding to the bolt insertion hole 2b is formed in the web portion of the hat-shaped main body 5a.

The center of the lower surface of the plate 4 is welded to the upper surface of the outer flange 5b of the connector 5, and both sides 4a*4a are arranged to protrude outward from the side door pieces 5c, 5c.

By fitting the hat-shaped main body 5a of the connector 5 into the ridge beam 2, the bulge 3a of the roof board 3 is fitted into the notch recess 5d of the connector 5, and the side door of the connector 5 is fitted. The lower end edge of the piece 5c is placed and engaged with the upper end edge of the roof plate 3, and the bolt 6 is passed through the bolt insertion hole 2b of the ridge beam 2 from the indoor side and screwed into the screw hole 5e of the connector 5, thereby making the connection. At the same time as fixing the fixture 5 to the ridge beam 2, the side door piece 5c of the connecting fixture 5
and the outer flange 2a of the ridge beam 2 press and clamp the upper edge of the roof board 3.

As a result of this configuration, the following effects are obtained.

That is, (1) Since no holes are made in the board 4 or the roof panel 3, there is no risk of rain leakage.

(2) The board 4 and the roof board 3 can be fixed to the ridge beam 2 from the indoor side using the bolts 6, making the construction easy and safe.

(3) Since the upper edge of the roof plate 3 is continuously pressed against the outer flange 2a by the door piece 5c of the connector 5, the roof plate 3 can be firmly fixed even with a small number of bolts 6.

This invention can be applied to all prefabricated buildings such as garages as well as storerooms.

As described above, the roof structure of the prefabricated building of this invention consists of a hat-shaped ridge beam installed horizontally with the opening facing upward, and a hat-shaped ridge beam with the upper edge placed on the outer flange of the hat-shaped ridge beam. A pair of roof plates tilted downward on both sides of the frame, and a lower end edge of a side door piece formed by fitting the hat-shaped main body into the hat-shaped ridge beam and bending the tips of both outer flanges downward. a connecting tool that is engaged with the upper edge of the upper surface of the roof plate; a board that is fixed to the top surface of both outer flanges of the connecting tool; Because it is equipped with bolts that connect the two, it has excellent rain protection performance and is safe and easy to install.
